A final comment. I had the problem the first time on Safari, but today I ghave tied IE on 7 different computers. No go. I am trying to give different folks on different operating systems access. Just want to be proactive.
pdo_mysql extension is installed and PHP cache accelerators are not.
Evo doesn’t use pdo, and as far as I know there are no issues with Evo and cache accelerators. There do seem to be an awfully lot of problems with TinyMCE lately, though.
